The officer, who officials are not identifying, was on routine patrol around 8:00 p.m. Monday night, Westmoreland County District Attorney John Peck said Tuesday. The officer noticed two men inside a Dodge car parked at Hilltop Park, which was closed for the day. Peck said the officer noticed the driver, 21, and passenger, 20, moving inside the vehicle. He ordered the men to show their hands.

"As he was exiting the vehicle, he noticed they were moving back and forth, perhaps either putting something underneath the seats or the dashboard or taking something from those areas," Peck said.

The officer demanded the men show him their hands a second time, Peck said, but they didn't. The officer told them to shut off the car but they didn't, instead putting it in reverse and then drive.

"He felt he had no place to retreat at that time. The vehicle was coming at him at a high rate of speed. He pointed his firearm at the vehicle and fired, we believe, two times in the windshield at the vehicle approaching him," Peck said.

He added the officer then fired five more rounds into the driver's side window. The passenger was shot in the right bicep. The passenger was treated and released from Forbes Regional Hospital in Monroeville. The driver wasn't hurt.

Police are not releasing the name of the two men inside the vehicle, and they are not facing charges right now. Peck said he will review all of the evidence before determining if the men should be charged and if the officer followed protocol.

"That's one of the issues that needs to be resolved as well, whether this shooting was completely justified. If firing at the individuals in the vehicle was justified," Peck said.

The district attorney's office detectives are handling the investigation. North Huntingdon Police Chief Andrew Lisiecki directed all questions to county detectives.
